Sand Dollar Spiny Sea Urchin EchinoideaThe Sand Dollar Spiny Sea Urchin (Echinoidea) is a unique and fascinating marine invertebrate. Originating from tropical and subtropical ocean regions, this urchin has a flattened, disk-like body covered in short, dense spines that give it a distinctive appearance. Unlike many other sea urchins, the Sand Dollar Spiny Urchin has very small spines that are not sharp or venomous, making it a relatively docile species. It is an herbivore, feeding primarily on algae and detritus that it collects with its tube feet. This urchin is generally peaceful and can be kept with a variety of other reef-safe invertebrates and small, non-aggressive fish. However, it may compete for food and space, so appropriate tank mates should be selected carefully.Keeping a Sand Dollar Spiny Urchin requires an intermediate level of aquarium experience. It needs a well-established marine aquarium with stable water parameters, including a pH of 8.1-8.4, temperature of 72-82°F, and specific gravity of 1.023-1.025. Regular water changes and a strong protein skimmer are also essential for its long-term health and well-being.Overall, the Sand Dollar Spiny Sea Urchin is a unique and visually appealing addition to a marine aquarium, but its care requirements should be thoroughly researched and understood before attempting to keep one.

These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.

Works like original equipment
Size: 16 Line Spools+4 Caps
Seems to handle the same work load as the manufacturer part. Good quality fit and design. No problems installing the string on the trimmer head. Definitely worth the purchase.
